  1. The POISONING of Rango Science Lab

  2. Introduction

  3. Introduction Rango has been poisoned! I must figure out who poisoned him by testing the crime scene objects. I know that there was a clear liquid, a bent piece of metal, a fragment of meat, and white powder. Whoever committed the crime must have used these things. I will test these things out, and I will find their physical and chemical properties to figure out who poisoned Rango.

  4. Hypothesis

  5. Hypothesis If Rango was poisoned, then Darth Vader is behind it, because he used objects that were found at the crime scene.

  6. Materials

  7. Materials • In this lab, we use the hot plates, scoopla, well plate, forceps, beakers, stirring rod, eye dropper, eye drop bottle, balance, graduated cylinders, test tubes, test tube racks, microscope, regular hot dog, light hot dog, 98% fat free hot dog, iodine, hydrochloric acid, sodium bicarbonate, sucrose, acetic acid sodium polycarbonate, VernierLabquest, temperature probes, conductivity probes, plastic, zinc, aluminum, magnesium, iron, and sulfur.

  8. Procedures

  9. Procedure • Drink lab • 1. gather materials (all liquids in sheet, conductivity probes, matches, etc.) • 2. Observe and record waters properties. • 3. Look to see its optical properties. • 4. Look to see if its homo or heterogeneous. • 5. Go to the cart to see its boiling point (it will be on the screen) • 6. Mix with powder and record its reactivity. • 7. Your teacher will take matches and see weather or not the liquid is flammable. • 8. Repeat 1-7 for the rest of the liquids.

  10. Procedure • Powder Lab • 1. Gather materials (all powders on sheet, water, microscopes, vinegar, matches, etc.) • 2. Observe and record sugar’s properties. • 3. Mix sugar with water to find its solubility. • 4. Look at the sugar under the microscope to see its crystalinity. • 5. Go to the board to see its melting point (on index cards) • 6. Feel sugar to find its texture. • 7. Mix sugar with baking soda to find its reactivity. • 8. Your teacher will take matches and find its flammability. • 9. Repeat 1-8 for all other powders.

  11. Procedure • Wraps Lab • 1. Gather materials (Wraps on sheet, conductivity probes, 3 beam balance, baking soda, matches, etc.) • Observe and record plastic’s properties • 2. Look to see if plastic is homo or heterogeneous. • 3. Find conductivity by placing conductivity probes on each side of wrap. • 4. Find mass with triple beam balance. • 5. Feel plastic to see its texture. • 6. Find reactivity by putting plastic in hydrochloric acid. • 7. Your teacher will take matches to find the flammability. • 8. Repeat 1-7 for other wraps.

  12. Procedure • Hot Dog Lab • 1. Gather materials (hot dogs on sheet, NAPKINS! Conductivity probes, iodine, matches, etc.) • 2. Observe and record hot dog’s properties • 3. Find mass on a triple beam balance. • 4. Find conductivity with conductivity probes. • 5. Look to see its color. • 6. Squeeze hot dog and find its mass with a triple beam balance. • 7. Find reactivity by putting in iodine. • 8. Teacher will find flammability with matches. • 9. Repeat 1-8 for the other hot dogs.

  15. Data

  16. Data 8 flammable objects 40 % 12 objects aren’t flammable 60%

  17. Conclusion

  18. Conclusion • Darth Vader was not the person who poisoned Rango. These findings disproved my hypothesis. He did not use the sodium bicarbonate and the regular hot dog. Instead, he used the sodium chloride and the 98% fat free hot dog. It is false that Darth Vader poisoned Rango, because his materials didn’t match the crime scene materials. I know this because Dorothy used 2 different thing than Darth Vader. Her powder was sodium bicarbonate and he hot dog was a regular hot dog. That way you know that Vader’s objects and Dorothy’s objects are different. • There were a couple of limitations on our equipment. We didn’t use our Finn material safety/data binder. Also, students weren’t able to find melting or boiling points or flammability on their own. Another experiment that could have been performed is how much of the item was used to poison Rango.
